MECHANICAL DETONATING TOY.

Speccation of Letters Patent.

Patented May 29, 1906.

Application filed July 26,1905, Serial No. 271,295.

To all whom t may concern:

Be it known that I, vWILLIAM H. JOHNSON, a citizen of the United Statesof America, and a resident of Brandon, in the county of Rutland landState of Vermont, have invented certain new' and useful Improvements inMechanical Detonating Toys, of which the following is a full, clear, andexact description.

This invention relates to a device adapted to carry a series ofpercussion-caps usually supported at the lower end of a stick or caneand including a striker or hammer for successively operating against thecaps to explode them and comprising means for the automatic intermittentadvancement of the ca s.

One object of the invention is to render the device adaptable for theengagement therewith of disks or circular plates having marginalcircularly-arranged series of caps so einployed that the diskconstitutes a shield or guard for the movable parts of the mechanism,'preventing the corroding explosive from which the caps are made fromhaving a detrimental effect on the device, especially in a manner toimpair the operativeness thereof.

Another object of the invention is to constructy the device in a mostsimple, cheap, and'practical manner.

Furthery advantages are attained in and by the parts organized asillustrated and hereinafter described." c

` The invention primarily consists in a device of the characterdescribed of the combination with asupport, a hammer pivoted to saidsupport, and a ratchet-toothed cap-disk carrier rotatable on saidsupport, of a pawlcarrier having a reciprocatory movement relatively toand projecting below the lower end of said support provided with amember to engage said hammer and having a pawl coacting with saidratcheted cap-disk carrier.

The invention furthermore consists in certain more specific combinationsand arrangements of parts and the constructions of certain of the parts,all substantially as hereinafter Ifully described, and set forth in ltheclaims.

The new cap-detonating device is illustrated in the accompanyingdrawings, in which- "Figure l is a perspective view of the same thecap-carrying relative position as used in the act of hring. Fig. 2 is afroht view of the novel portion of the device with disk or plate absent,lthe thereof, however, being in'- dicated by dotted lines. Fig. 3 issubstantially a central vertical longitudinal section as taken on theline 3 3, Fig. 2. Figsxlf and 5 are face views of cap-disks, showing'f'e'atures of construction hereinafter referred to.

Similar characters v'of reference 'indicate corresponding partsin all ofthe views.

In the drawings, A'represents a support or frame having the circularforwardly-opening recess a therein made with a central` for-Awardly-extending boss C and withi down'- wardly-extending separatedear-lugs b b and i the upwardly-extending shank d, which has acane-receiving socket c,

leading downwardly from its open upper endto saidrecess a, and saidsupporting-frame is'con.-

structed with an opening f in its lower por- ,tion, extendingfromcommunication withl said recess a to the space betweenthe saidear-lugs b'b. A three-membered hammer B is pivotally connected to andbetween said ear-lugs for a swinging movement, so that its upperstriking end may impinge against the front face of the frame justbelow'the middle lower portion of the recess a. Theratchetwheel C, whichconstitutes a rotatable capdisk carrier, is pivoted for rotation on thefront of said boss c and has forwardly-projecting pins or studs g g,which are shown' as set diametrically opposite each other. -D representsa pawl-carrier located in said recess and having an apertured middleportion embracing said recess c, andv this pawl-carrier is constructedwith anupwardly-extending shouldered member h and with adownwardlyextending member i, projecting 4downwardly and in a verticalline through said opening below the lower ends of the ear-lugs andhaving the forwardly-return bent extremityj for engagement with thehammer B, `as most clearly shown in Fig. 3. The spring-pressed pawl m ispivotally mounted on said pawlcarrier and has its point in engagementwith the said ratchet-toothed cap-disk carrier C. The spring n, locatedin said socketed shank, is in compression and reacts downwardly againstthe shouldered member ofthe pawlcarrier and serves normally to keep thelatter in its downwardly-extending position.

.IOO

`made of paper, cardboard, metal, or other material having thecircularly-arranged marginal series of separated lcaps or percussivelayers on its front face. The said disk has the diametrically oppositesmall perforations s s, whereby such disk may be engaged with theforwardly-projecting pins g g of the ratchettoothed cap-disk carrierwhen brought to the position represented in Figs. l and 3 of thedrawings, whereby said disk must necessarily partake of the rotationalstep-by-step -movements of the ratcheted carrier-wheel C, and alsocovers and protects the chamber or` recess a, within which the mostactively-operable and sensitive parts o1 the device are located, andthus when the caps are exploded none of the gas or smoke therefrom canhave entrance into the portion of the mechanism within the circularrecess a, which is behind and effectually covered by the cap-disk.

As shown in Figs. 4 and 5, the cap-disks have marginal cuts or incisionst, those in Fig. 5`being re resented as having a substantial width, andthe construction of the capdisk with these cuts is to the end ofisolating each cap fromthe next, so that the paper or other materialfrom which the disk is consti.- tuted is'not rendered a conductor tolead the fire or gas from the exploding-cap to the one next behind forthe premature iiring of the latter.

The action of the device is apparent in Fig.. 1. By thrusting the devicein a downward direction against the ground or floor the forwardly-turnedlower end projection y of the then relatively upwardly movingpawl-carrier swings the hammer to bring its striking end forciblyagainst the cap, properly positioned to receive the hammer-blow. Theelevation which in this action is imparted to the pawl-carrier causesthe'pawl m to engage a new tooth of the ratchet-wheel C, so that whenthe device is bodily elevated from the floor or ground the pawl-carrierhaving its downward returning movement under the reaction of theI,spring m will cause a rotational movement of the ratchet-wheel to theextent of one tooth, which gives a corresponding movement to the disk tobring the next cap to position to be struck by the hammer, it of coursebeing understood that the spacings of the ratchet-teeth and caps are tocorrespond.

Having thus described my invention,what I claim, and desire to secure byLetters Patent, is-
